Material: PC + Metal

1. CT7601CR
Compact 48-pin package; supports 384 kHz/DSD256; low power consumption (45 mA); driverless, universal compatibility.
2. ES9018K2M
A low-power, high-performance 32-bit stereo For DAC chip. Features a 127 dB SNR, -120 dB THD+N, and a current draw of only 40 mA. Supports 32-bit/384 kHz PCM and DSD256 decoding; includes a built-in programmable FIR filter and jitter eliminator.

3. 97220 Headphone Amplifier
A stereo headphone amplifier/ driver chip designed without output coupling capacitors. It emphasizes high fidelity, low power consumption, and low noise, making it suitable for portable devices such as smartphones, tablets, and audio players.

4. Gold-plated 3.5mm Headphone Jack
Gold is virtually inert to oxygen, sulfur, and chlorine, ensuring clean contacts even in humid, salt-spray, or industrial environments. It prevents intermittent disconnections caused by oxidation during repeated plugging and unplugging.

5. GND Ferrite Bead
Uses a ferrite bead to connect the computer's GND to the module's GND. This blocks high-frequency ripple-generated by high-speed switching in digital chips-from coupling into the analog front-end via the ground plane, thereby improving the SNR For ADC, audio, or RF circuits.
